María Trinidad Sánchez (Spanish pronunciation: [maˈɾi.a tɾiniˈðað ˈsantʃes]) is a province of the Dominican Republic.

María Trinidad Sánchez was the first woman incarcerated and executed by Pedro Santana, a Dominican annexionist president.

It is of a great tourist vocation due to the large number of beaches it has on its coasts and the beautiful natural landscapes it has.

Traditionally, the economic production of area was based on livestock, fishing and agriculture and was carried out by sea with Puerto Plata.

Then in the decade of the 80s, the increase in tourist activity produced a great displacement of the rural population towards the city, so that agricultural production decreased considerably, projecting the economy of the municipality towards consumerism and not towards production, which allowed wealth to be concentrated in tourism and commercial enterprises.
